Question- Technology
- What are the key technologies being used in solar module manufacturing globally? Which companies or regions are leading in terms of technological innovation, and can Indian companies access and adopt these newer technologies?
- Global Transition to N-Type Solar Technology- Even in China and globally, n-type solar cell capacity is still below 50%. Is this transition happening smoothly, or are there unexpected challenges that could disrupt the shift from p-type to n-type technology?
- Challenges of Transitioning from P-Type to N-Type Solar Technology- What are the costs and challenges involved in transitioning manufacturing facilities from p-type to n-type solar cells? If India has an apparent oversupply of p-type capacity, is this truly the case if p-type technology is being phased out? How quickly can manufacturers shift from p-type to n-type technologies, such as TOPCon? Who are likely to be the winners and losers in this transition?
- The Indian Institute of Technology (IIT) Madras has developed low-cost, high-efficiency solar cells using N-type Czochralski silicon wafers. Do you foresee such homegrown technologies helping propel India to the solar industry’s forefront?
- It seems like India’s rise in manufacturing capacity is benefitting Chinese equipment manufacturers/ consultants, and India has become part of their product lifecycle, wherein we’re concentrating more on Mono PERC because of its price advantage and ease of production. On the other hand, the Chinese have moved on to TOPCon and HJT completely in terms of production because of the superior technology and their efficiency in producing these now. In a few years, India will be scaling TOPCon capacity when the Chinese move to HJT/ newer technology. Given this trend, how can India ensure it stays competitive in the global solar manufacturing race, rather than constantly trailing behind China?
